Radiation induced F-center and colloid formation in synthetic NaCl and natural rock salt: Applications to radioactive waste repositories

Chemical Decomposition of High-Level Nuclear Waste Storage/Disposal Glasses Under Irradiation

“…implantation (see literature cited in [ 133) and have been diversely attributed as being related to oxygen, sodium, or carbon. Since model glass CSG contains a relatively large amount of sodium oxide and there is a concern for the possibility of sodium metal colloid formation under irradiation (as in the case for the alkali halides [6,7]), the temperature dependence of the linewidth was recorded to look for telltale signs of discontinuous changes at the melting point of sodium, 370.5 K. The results are shown as the open symbols in Fig. 9, in juxtaposition with ESR data (solid circles) for sodium colloids in NaN, [26].…”

“…Long-term and low-dose-rate tests need to begin now s o that the low-dose-rate hypothesis o f Levy et al, 1984, can be tested.…”
